Dt-swiss DT Swiss G 1800 Spline® DB 25 SHIMANO HG / SRAM XD™ Gravel-Hinterrad 27,5“/650B

Be ready for UNPAVED ADVENTURES!
With the launch of their gravel-dedicated system wheels, the wheel specialists of the traditional manufacturer DT Swiss have opened up a new territory that used to be reserved for mountain bikers in the past but today fascinates adventurous road cyclists.

The G 1800 Spline® DB 25 rear wheel represents the entry into DT Swiss’ special wheel family and opens the door to a completely new world away from tarmac and paved roads.
The robust alloy rim is lightweight, stiff and impresses with outstanding durability for your first adventures on the gravel roads of the world. In this way, it perfectly combines riding dynamics with fun without burdening your budget. An inner rim width of 24mm additionally provides a large tyre volume, which takes the comfort on demanding gravel roads to a new level.
Optimised for use with powerful disc brakes, the rim rotates around the proven DT 370 rear hub that provides reliable propulsion and good power transfer thanks to solid bearings and a reliable 3-pawl freehub system. Aerodynamic DT Swiss aero comp® straight pull and DT Swiss new aero® straight pull bladed spokes give the entire wheel system a perfect balance of comfort and stiffness.

For maximum off-road performance, the DT Swiss G 1800 Spline® DB 25 wheel also offers excellent tubeless compatibility. When used without tubes, you’ll benefit from less weight, improved puncture resistance, reduced rolling resistance and increased comfort, since you can ride with lower air pressure on unpaved roads.
So leave the paved roads behind and discover unknown territory. The G 1800 Spline® DB 25 rear wheel is a reliable companion!


Technologies:

• TUBELESS:
All DT Swiss wheels are tubeless ready. The profiles of the DT Swiss rims are specially designed for tubeless use. The rim profile makes it easier to fit the right tyre and ensures a perfect fit. The tubeless system of the rim consists of DT Swiss tubeless ready tape for sealing and a DT Swiss tubeless valve in a length that complies with the rim. When using tubeless ready tyres, a compatible sealant must be used. However, it is also possible to use a conventional combination of tyre and inner tube.

• BEARINGS:
Having learned from years of experience, DT Swiss only uses durable cartridge bearings without bearing play adjustment. DT Swiss hubs are designed to have the optimum axial and radial bearing play when they are properly installed. The correct preload of the bearings to compensate for the clamping force of the wheel mounting system is the basis for a play-free hub with minimum friction.

• PRO LOCK®:
DT Pro Lock® prevents the spoke-nipple connection from loosening. In the Pro Lock® process, a special dual component adhesive is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and then hardens completely within a few hours. Re-truing the wheel is possible, yet it will cause a slight decrease in the adhesive power each time.
